This biography describes Shelley's life-in-thought. It dispels the popular conception of him as a vague dreamer and reveals a radical thinker passionately concerned with practical questions of politics, social abuses, and the underlying questions of good and evil, free will and determinism. The Shelley so revealed is a poet of greater range, insight, and power than has hitherto been acknowledged.
